SHUTTLE FOB, CARPET-WEAVING LOO IVIS.

Application filed November 22 1923. Serial 110,676,331,

Be it known that I, LUIGI ,QUAREsI A,a Subject of the King of Italy, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Shuttles for Carpet-Weaving Looms, of which the following is a specification.

-This invention relates to new and useful improvements in shuttles for carpet weav ing loo-ms.

An important object of the invention is to provide a shuttle adapted for use in a carpet weaving loom to form one selvage edge of the same. A further object of the invention is to provide a shuttle for a needle type loom which is adapted for feeding a cord through the looped ends of the weft to form a selvage edge, the said selv-age edge being opposite to the edge formed by the needles.

A still vfurther object of the invention is to provide a shuttle having a cord or thread guide which will carry the latter well out from the side edge of the shuttle body and substantially on a horizontal plane with the top surface thereof.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a top plan view of the shuttle embodying this invention,

Figure 2 is an edge ele-va-tional view of the shuttle which carries the cord guide,

Figure 3 is a bottom plan View of the shuttle shown in Figs. 1 and 2,

Figure 4 is a longitudinal sectional view taken upon lines IV-IV of Fig. 2,

Figure 5 is an end elevational view of the end of the shuttle carrying the cord guide,

Figure 6 is a transverse sectional view taken upon line VIVI of Fig. 1, and s Figure 7 is a transverse sectional view taken upon line VIIVII of Fig. 1.

In the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention,the numeral 5 designates the bottom wall of the body. portion of the shuttle which is formed integrally with the tapered end portion 6 which has a transversely extending cutout portion 7 formed therein, The numeral 8 I designates the top wall of the body portion of the shuttle which is adapted to be positioned within the cutout portion 7 of the tapered end portion 6 and to extend in spaced parallelism with the bottom wall 5. This top wall 8 is formed of a separate piece and r is secured to the remaining portion of the body of the shuttle by the rivets or pins 9. By inspecting Figs. 1 to 3 inclusive and 5, it will be seen that one corner of the top wall 8 is formed with a cord guide 10 that is slightly offset upwardly from the plane 00- cupied by the said top walland is provided with a beveled end portion 10*. Said cord guide 10 is provided with a cord receiving opening 11 which is formed therein at an acute angle to the transverse axis of the said guide.

Positioned between the bottomand top walls 5 and 8 respectively is a bobbin 12 which is removably, rotatably retained in its proper position by means of the pin 13 d which is provided with an enlarged externally threaded head let, the said threads engaging the wall of an internally threaded opening 15 formed in the top wall 8. It will be seen, by inspecting Figs. 4C and 7, that one of the rivets 9 carries a. tension element 16 for the bobbin 12. This tension element is formed from a sheet of suitable spring material, such as steel, and is bent into substantially cylindrical formation, as at 17, for being retained upon the rivet 9, carrying the same. One of the free ends of this tension element 16 is adapted to bear against the inner face 18 of the tapered end 6 and is designated by the numeral 19. The remaining free end of the tension element 16 is bifurcated, as at 20, for providing a pair of spring arms that frictionally engage the peripheral edges of the sides of the bobbin 12 for preventing free rotation of the latter.

There is further provided a tension element for the cord which is positioned between the bottom and top walls 5 and 8 respectively laterally of the bobbin 12 and consists of a pair of disks 21 which are bevelled at their inner peripheral edges for forming a groove 22. These disks 21 are rotatably mounted upon a pin 23 which is provided with an enlarged externally threaded head 24, the said threads being adapted for engaging an internally threaded aperture 25 formed in the top wall 8. Interposed between the inner face of the enlarged head 24 and the outer face ofone of the disks 21 1s a coil spr1ng26 which encircles the pin 23 and exerts a greater or less amount of pressure against the outer.

by the bobbin 12 is tobe passed around the groove 22 from the inner side of the same to the outer side and over the rivet 9 which is positioned adjacent thereto. This cord is then intended to be passed under the stationary sleeve 9, carried by one of the rivets 9 and then outwardly through the angularly extending guide opening 11 inthe guide 10. t will be seen, due to the formation of the cord guide 10, that the said; cord, as it leaves the shuttle, will be fed therefrom at apoint spaced from the side edge of the top wall 8 and on aplane with the top face of thesaid wall. 1

It is to be understood that the form of this invention herewith shown "and described is to be taken as a. preferred example of the same, and that various changes in the shape, size, and arrangement of parts a may be resortedto without departing from the spirit of the invention or the scope of the subjoined claims. I V

Having thus described the invention, I

I claim 1. In a shuttle of the type described, a

body port-ion comprising spaced top and bottom walls, a bobbin positioned between said Walls, and a guide member carried by the edge of one of said walls projecting outwardly therefrom. and offset from the plane occupied by said wall.

2. In a shuttle of the type described, a body portion comprising spaced Walls, a bobbin removably positioned between said walls, a cord guiding member carried by one of said walls and projecting outwardly therefrom, said cord guiding member having an aperture formed therein.

3. In a shuttle of the type described, a body portion consisting of spaced top and bottom walls, a bobbin removably' rotatably carried by said walls, a tension means for said bobbin, a cord tension means carried by said walls laterally of said bobbin, and a cord guiding member carried by the edge of one of said walls and projecting outwardly therefrom.

a. In a shuttle of the type described, a body portion consisting of spaced top and bottom walls, a bobbin rotatably removably positioned between said walls, a resilient tension means for said bobbin, a resilient cord tensioning element positioned between said walls, and a cord guiding member car ried by the edge of one of said walls and projecting outwardly therefrom in an offset position from the plane occupied by said Wall.

In testimony whereof I aflix my signature.
